Can you teach me how to changed the gpu feom?

[PTT31]

          Umm i know its late but there is a weird bug ive found on this card using linux that enables nvenc but changing any srtting in obs breaks it forever unless u do a syatem reinstall... 

I installed a p104-1008gb card on ubuntu unity 22.04 with nvidia drivers "525.xx". With only this card in the system. A while later i turnes off my syatem and added my old p106-100 into a second pcie slot. It detectwd but didn't use the p106-100 but for some reason nvenc actually worked. When i changed the gpu feom "0" to "1" this broke for that install.

Also when it did work it said in obs "nvenc" instead of "nvenc/h.264" so i do not know why this workes but it worked aimilarly in 16.04. So i think its possible that its using the laptop edition of nvenc waiting for the x264 to be run that way and thus errors out and adding teh second desktop gpu enabled desktop functionality but then broke it? I donno anything technical bit could mean ti just needs to be forced into desktop mode via a patch?

I don't unserstand what you're asking. Namely cause i'm new to this website and it doesn't seam to show me any comment but my own. So what are you asking?

But if you mean how to set it up

• have p104 inside pc.
• install the ubunut unity as normal.
• make sure igpu is set as primary in your bios. As a "safeguard"
• use "ctrl + alt + t" to open a terminal.
• run "sudo apt install nvidia-prime && prime-select Nvidia"
• run the commands in terminal "device-drivers" or add the graphics team ppa and use a command to install the nvidia driver.
• once installed restart the pc logging out wont work as well

Note

• if you get a black screen, use alt+ f2 to enter tty1 terminal and use sudo prime select query. There will give u "intel" "nvidia" or a 3rd option. The 3rd option may be nessesary if nvidia black screens you. Nvenc usually doesn't work. But this is thr process to install the p106 or p104 if thats what you mean.

You need to kind of add stuff per program(its weird) if u use middle option but the nvidia mode usually works fine.

• also no idea why nvenc worked with 2 cards once. But it doesnt work so far
